METALLIC DRUM.

Toall whom it may concern:

Be it known that I, HENRY L. GERSTEN- BERGER, a citizen of the United States, residing at Roselle, in the county of Union and State of' New Jery, have invented a new and useful Improvement in Metallic Drums, of which the following is a specification.

The resent invention relates to improvements 1n metallicV drums, and is fully described inthe following specification and illustrated in the accompanying drawings, in 'which- Figure 1 is a perspective view of a drum embodying the present invention;

Figure 2 isa sectional detail view showing the chime and head of the drum;

Figure 3 is a detail sectional view of a modified form of construction;

AFigure 4 is a detail sectional view through the/head of a drum of the same form of construction as shownin Figure 2; and

Figure 5 is a detail sectional view through the head of the drum, the form of construction being the same as that of Figure 3.

Referring more particularly to the construction of the drum, the numeral 10 indicates the body ofa drum, which may be substantially cylindrical in form and provided with hoops 11, which may be, if desired, rolled into the bod of the drum. Near each end the body of t e drum is rolled or pressed outwardly to form a narrow ledge,

or shoulder, 12, upon which rests the sheetv or headl 13 of generally circular form. A weld is formed entirely around the head at its point of contact with the chime portion of the body above the shoulder 12, the added weld metal being indicated by the numeral 14. The means the drum, as above described and illustrated in the drawings, is the saine for both ends of the drum.

The chime of the drum extends upwardly above the head of the barrel and is, in the orm of construction shown in Figures 2 and 4, rolled over a steel hoop 15 of circular 4cross-section. The chimes at both ends of the drum are reinforced in the same manner. In the head of the drum the'spuds for the bung and vent holes are seated upon' conical projections formed or pressed in the head, the interior surfaces of which projections are concave,

barrel to empty the same, its contents will all drain perfectly through the bung or vent holes. Annular seats are formed in' the Specification of Letters Patent.

for attaching the head of so that on turning over thev bases of the bung` and 17, respectively,

tiguous surfaces of the drum-head, and form' therewith a continuous conical surface. A weld 18 around the bung hole Spud/16 secures it in position, and a. similar weld 19 secures the vent hole spud 17 in position. The plugs 20 and 21 are screwed into and close the bung and vent holes in the respective spuds, suitable gaskets 22, 22 being provlded for both. The proportions of the parts 'are' such that the outer surfaces of the bung and vent hole spuds are below the level of the top of the chime. Near the base of the chime, at a point below the openings of the bung and vent hole spuds, a plurality of openings 23, 23, are formed in the chime, and prevent the accumulation of liquid on the head of the drum to a level which would permit it to enter the bung and vent holes.

In the -form of construction illustrated in Figures 3 and 5, the construction of the heads of the drum, the means for securing,r them to the drum, and the construction of the bung and vent hole parts are substantially the same as has been described in connection with the construction of Figures 2 and 4. In thisform of construction, however, the upper portion of the chime is reinforced by turning or spinning it inwardly' over the top oliy a circular ribbon, or hoo 24, of flattened cross-section. At suitab e intervals around the chime, grommets .25 pass through the hoop 24 and the chime, and secure these parts together.- These grommets are positioned below the top of the" bung and vent holes, the openings through the grommets thereby preventing water accumulated on the head of the drum- Patented Apr. 25, 1922. Application led April 28, 1920. \Serial No. 377,350.

' beyond said shoulder to form a chime,

face of the projection, and a closing plug adapted to seat in said spud.

2. In combination, la drum body formed near its end with a shoulder and extended a reinforcing hoop within the chime, a head seated upon the said body shoulder, said head being provided with interiorly conl having an cave conical projections, spuds seated upon the said projections and having their interior surfaces flush with the internal surfaces of said projections and of vlike concavity, the ,openings of said spuds 'being below the topuof the chime, closures' for said openings,fapertured means for securing the chime and reinforcing hoop together, saidl means being ski-.positioned that the openings therethrough are lbelow the level of the openings of the spuds.

3. In combination, a drum body, a head opening therein, the drum body being lextended beyond the head to form a chime, reinforcing means adjacent the chime, 'apertured means for securing the chime and reinforcing meansv together, said securing means being so positioned that the openings therethrough are below lthe level of the opening in the head. HENRY L. GERSTENBERGER.
